A semiconductor device has a substrate. A semiconductor die including a photosensitive circuit is disposed over the substrate. A shield is disposed over the substrate and semiconductor die with a first opening of the shield disposed over the photosensitive circuit. An outer section of the shield is attached to the substrate and includes a second opening. An encapsulant is deposited over the substrate and semiconductor die. The encapsulant extends into the first opening and a first area between the shield and substrate while a second area over the photosensitive circuit remains devoid of the encapsulant.

Semiconductor device and method of forming an optical semiconductor package with a shield structure

A semiconductor package is disclosed. The package includes a package substrate having top and bottom major package substrate surfaces, the top major package surface including a die region. A die having first and second major die surfaces is attached onto the die region. The second major die surface is attached to the die region. The first major die surface includes a sensor region and a cover adhesive region surrounding the sensor region. The package also includes applying a cover adhesive to the cover adhesive region on the first major die surface. A protective cover with first and second major cover surfaces and side surfaces is attached to the die using the cover adhesive. The second major cover surface contacts the cover adhesive. The protective cover covers the sensor region. The protective cover includes a recessed structure on the second major cover surface. The recessed structure is located above die bond pads on the die to create an elevated space over peak portions of wire bonds on the die bond pads. An encapsulant is disposed on the package substrate to cover exposed portions of the package substrate, die and bond wires and side surfaces of the protective cover, while leaving the first major cover surface exposed.

Reliable semiconductor packages

A method for forming a semiconductor package is disclosed. The method includes providing a package substrate having top and bottom major package substrate surfaces, the top major package surface including a die attach region. A die having first and second major die surfaces is attached onto the die attach region. The second major die surface is attached to the die attach region. The first major die surface includes an die active region and a cover adhesive region surrounding the die active region. The method also includes applying a cover adhesive to the cover adhesive region on the first major die surface. A protective cover with first and second major cover surfaces and side surfaces is attached to the die using the cover adhesive. The second major cover surface contacts the cover adhesive. The protective cover covers the die active region. The protective cover includes a discontinuity on at least one of the side surfaces. An encapsulant is disposed on the package substrate to cover exposed portions of the package substrate, die and bond wires and side surfaces of the protective cover, while leaving the first major cover surface exposed. The discontinuity enhances adhesion of the encapsulant to the protective cover.

A semiconductor package and a method for forming a semiconductor package are disclosed. The semiconductor package includes a multi-layer package substrate having interconnect structures embedded therein. A sensor chip having an image sensing element is disposed on a top surface of the package substrate, and an integrated circuit is mounted to a bottom surface of the package substrate. The integrated circuit is a flip-chip assembly. The sensor chip is electrically connected to the integrated circuit. An adhesive material bonds a transparent covering member to the sensor chip to enclose the image sensing element.
